Define a jenny.properties file using this
sample properties file
as a template.
Copy this file to your work directory and give it a more appropriate
name. Then edit the file so it reflects how you want Jenny to generate
your class files.

Now that you've created your "personalized" files, you are ready to use them.

You should be able to see a Java source file for each of your tables
in your database. Compile and use the generated source as if you wrote it yourself!
For example:

Let's say that you have a database named "rentals".
Within the rentals database you have tables named "videos",
"compactDisks", "booksOnTape". After you run Jenny, you should see a
subdirectory named rentals (the subdirectory is defined by the
properties file) which contains classes named "Videos",
"CompactDisks", and "BooksOnTape".
Each of these classes contains methods with the same signature as the
methods in DBFacade, which have been overridden.
Now you can create a method in your code like:

// pass in an serial number and get back
// the title of the video that you are searching for.
private String getVideoTitle( int serialNumber )
{
return VideosTable.getRow( serialNumber ).getTitle();
}

and you won't have to worry about getting the wrong thing back because
someone changed the name of the column from "Title" to "Titles" or "TITLE" or
having to change the code in the getTitle() method from

out.print( rs.getString( "Title" ) );

to

out.print( rs.getString( "Titles" ) );

everywhere you've used that column name.
